BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum x morifolium,typically grown as a cut flower Chrysanthemum and hereinafter referredto by the name ‘DLFMONE3’.

The new Chrysanthemum plant is a product of a planned breeding programconducted by the Inventor in Maasdijk, The Netherlands. The objective ofthe breeding program is to create new cut flower Chrysanthemum plantswith numerous attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination inJanuary, 2009 of a proprietary selection of Chrysanthemum x morifoliumidentified as code number db 35211, not patented, as the female, orseed, parent with a proprietary selection of Chrysanthemum x morifoliumidentified as code number db 13000, not patented, as the male, orpollen, parent. The new Chrysanthemum plant was discovered and selectedas a single flowering plant from within the progeny of the statedcross-pollination in a controlled greenhouse environment in Maasdijk,The Netherlands in July, 2010.

Asexual reproduction of the new Chrysanthemum plant by vegetativeterminal cuttings since July, 2010 has shown that the unique features ofthis new Chrysanthemum plant are stable and reproduced true to type insuccessive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have not been observed under allpossible combinations of environmental conditions and culturalpractices. The phenotype may vary somewhat with variations inenvironmental conditions such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘DLFMONE3’. These characteristics incombination distinguish ‘DLFMONE3’ as a new and distinct Chrysanthemumplant:

-   -   1. Upright plant habit.    -   2. Vigorous growth habit and rapid growth rate.    -   3. Dark green-colored leaves.    -   4. Uniform and freely flowering habit.    -   5. Strong upright flowering stems with numerous inflorescences.    -   6. Semi-double type inflorescences with quilled purplish red to        reddish purple-colored ray florets and yellow green-colored disc        florets.    -   7. Relatively tolerant to low and high production temperatures.    -   8. Good postproduction longevity.

Plants of the new Chrysanthemum differ primarily from plants of thefemale parent selection in ray floret color as plants of the newChrysanthemum have darker purplish red-colored ray florets than plantsof the female parent selection. In addition, plants of the newChrysanthemum have smaller inflorescences than plants of the femaleparent selection.

Plants of the new Chrysanthemum differ primarily from plants of the maleparent selection in ray floret color as plants of the new Chrysanthemumhave darker purplish red-colored ray florets than plants of the maleparent selection. In addition, plants of the new Chrysanthemum havesmaller inflorescences than plants of the male parent selection.

Plants of the new Chrysanthemum can be compared to plants ofChrysanthemum X morifolium ‘Delbrestar’, not patented. In side-by-sidecomparisons, plants of the new Chrysanthemum differ primarily fromplants of ‘Delbrestar’ in ray floret color as plants of the newChrysanthemum have purplish red to reddish purple-colored ray floretswhereas ray florets of ‘Delbrestar’ are white strongly tinged withpurple in color. In addition, plants of the new Chrysanthemum havequilled-shaped ray florets whereas than plants of ‘Delbrestar’ havespatulate-shaped ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of thenew Chrysanthemum plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type.

The photograph on the first sheet comprises a side perspective view of atypical flowering stem of ‘DLFMONE3’ grown as a spray-type cut flower.

The photograph on the second sheet is a close-up view of upper (top ofthe photographic sheet) and lower (bottom of the photographic sheet)surfaces of typical leaves (left) and inflorescences (right).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations andmeasurements describe plants grown during the late spring in ground bedsin a glass-covered greenhouse in Maasdijk, The Netherlands and undercultural practices typical of commercial cut Chrysanthemum production.Plants were initially given long day/short night treatments followed byshort day/long night treatments to induce flower initiation anddevelopment. During the production of the plants, day temperaturesranged from 18° C. to 25° C., night temperatures ranged from 20° C. to22° C. and light levels averaged 8 klux. Plants were grown assingle-stem spray-type plants and were nine weeks old when thephotographs and the description were taken. In the followingdescription, color references are made to The Royal HorticulturalSociety Colour Chart, 2015 Edition, except where general terms ofordinary dictionary significance are used.
